The nuget pm ui lets me make selections for things it will actually not install

[StingyJack]

Details about Problem

NuGet product used (NuGet.exe | VS UI | Package Manager Console | dotnet.exe): VSUI

NuGet version (x.x.x.xxx): VS 15.6.7

VS version (if appropriate): 15.6.7

OS version (i.e. win10 v1607 (14393.321)): Win 10, broken start menu edition

Worked before? If so, with which NuGet version: dont know

Detailed repro steps so we can see the same problem

1. Open a solution in VS. Solution has a nuget.config in the same folder with three sources defined. nuget.org, my in house repo, and a local temporary folder used for testing packages

2. Open the NuPM UI, it should show "Installed" list. The package source selected is for the local temp folder (because I selected it last time the window was open?)

3. Select a package from the installed list to install into a project that does not have it yet. Put a check next to the project in the projects list. Pick a version.

4. Click install.

Expected, the package I selected is installed.

Actual: the package is not installed and the output window says

Attempting to gather dependency information for package 'Our.BarcodeDecode.1.2.0.3' with respect to project 'UnitTest\OurDerviceHostTests', targeting '.NETFramework,Version=v4.6.2'
Package 'Our.BarcodeDecode 1.2.0.3' is not found in the following primary source(s): 'C:\yadda\localNugetTempPackages'. Please verify all your online package sources are available (OR) package id, version are specified correctly.`

And if you arent paying close attention, you wont notice the package didn't install.

All the sources are indeed available. If I change the source to the in house repo (where this package does live), it installs correctly.

The UI shouldnt let me make the selection if it wont execute the direction.
